This theory was originally suggested by Abraham Ortelius in 1596, and was later opposed to another theory based on paleomagnetic evidence, the polar wandering theory. This process is thought to be driven by another process whereby magma seeps out on ocean bottoms to form new crust, seafloor spreading, and its most notable proponent was Alfred Wegener. For 10 points, name this theory that was built on by the concept of plate tectonics, the idea that namesake land masses slowly move.
